WACKERLING - Wackerling Catalog of Early-Type Emission-Line Stars |
HEASARC Archive |
Overview
The Wackerling Catalog contains entries for 5326 early-type emission-line stars. Of these stars, 1424 have no spectral classification but are assumed to be of early type. Some 71 percent of the stars in this catalog can also be found in the Mount Wilson and the Mount Wilson-Michigan survey catalogs. The Wackerling Catalog contains numerous cross identifications to other designations (common name, HD, DM, LS, MWC, TON, HIL, WRA, HEN, etc.), rough spectroscopic types, magnitudes (visual and blue), and positions.The version of the Wackerling Catalog on which the HEASARC database is based was obtained from the ADC and differs in some respects from the original published version, notice.
Catalog Bibcode
1970MmRAS..73..153WReferences
Catalogue of Early-Type Stars Whose Spectra Have Shown Emission Lines; Wackerling, L.R. (Mem. Roy. Astron. Soc. 73, 153 (1970))Provenance
This online catalog was originally ingested by the HEASARC in July 1999, based on a machine-readable table obtained from the ADC/CDS data centers. It was updated in May 2020 to reflect updates to the spect_type_code values made by the CDS for improved database compatibility.Parameters
Wackerling
The Wackerling Sequence number based on the order in the published catalog,
i.e., in increasing RA (1900 equinox). Notice that this is seldom used in the
literature, and is not a recognized designation by the Dictionary of
Astronomical Nomenclature.
Name
A standard designation for the star, albeit in a somewhat condensed form in
some cases. If the listed name is a string of numbers, to determine the
actual full name, this has to be compared with the values of the other
catalog parameters: hd, dm, mwc, hpc, ton, ls, wray, and henize, in many
cases. For example, if name = '225095' and hd = 225095, then the full name
should be 'hd 225095'. In other cases, the listed name may be a
constellation-based designation such as the Bayer name (Greek letter +
3-letter abbreviation for constellation, e.g., OMI CAS for omicron
Cassiopeia), Flamsteed name (number + 3-letter abbreviation for
constellation, e.g., 10 CAS for 10 Cassiopeia), or variable star name (e.g.,
AX PER for AX Persei), or the name of the star in the HR or NGC Catalogs.
RA
The right ascension in the specified equinox. The positions in this database
were created using the B1950 equinox positions given in the original ADC/CDS
table. The precision of these latter positions given was to the nearest 0.01
minutes (0.6 seconds) in RA in the original table, notice.
Dec
The declination in the specified equinox. The positions in this database were
created using the B1950 equinox positions given in the original ADC/CDS
table. The precision of these latter positions given was to the nearest 0.1
arcminutes (6 arcseconds) in RA in the original table, notice.
LII
The galactic longitude of the star.
BII
The galactic latitude of the star.
Common_Name
The designation with which the source is normally referred. This name may be
a constellation-based designation such as the Bayer name (Greek letter +
3-letter abbreviation for constellation, e.g., OMI CAS for omicron
Cassiopeia), Flamsteed name (number + 3-letter abbreviation for
constellation, e.g., 10 CAS for 10 Cassiopeia), or variable star name (e.g.,
AX PER for AX Persei), or the name of the star in the HR or NGC Catalogs.
Common_Name_Flag
A flag for the common_name parameter which, if set to ':', indicates an
uncertainty exists in this designation.
HD
The Henry Draper catalog number.
HD_Component
A flag for the hd parameter, indicating for multiple systems which component
is being referred to ('A', 'B', etc), or, if set to ':', indicates an
uncertainty exists in this designation.
DM
The Durchmusterung (DM) Catalog name, where a 'BD' prefix refers to the
Bonner Durchmusterung (BD), a 'CD' prefix refers to the Cordoba
Durchmusterung (CD or CoD), and a 'CP' prefix refers to the Cape Photographic
Durchmusterung (CPD).
DM_Component
A flag for the dm parameter, indicating for multiple systems which component
is being referred to ('A', or 'P'), or, if set to ':', indicates an
uncertainty exists in this designation.
MWC_Or_AS
The Mount Wilson Catalog (MWC) or Additional Stars Catalog (AS) number.
Entries which contain just a number refer to the MWC, so that a value of '4'
implies a full name of 'MWC 4', while entries with a prefix of 'A' followed
by a number refer to the AS Catalog, so that a value of 'A 2' implies a full
name of 'AS 2'.
MWC_Or_AS_Flag
A flag for the mwc_or_as parameter set to ':'if the MWC or AS identification
is uncertain.
HPC
The Hiltner Polarization Catalog (Hiltner, W.A. 1956, ApJS, 2, 389) number.
HPC_Flag
A flag for the hpc parameter set to ':'if the HPC identification is
uncertain.
Ton
The Tonantzintla number, i.e., a reference to a star list published in the
Bol. Obs. Tonantzintla Tacubaya (except M1 from Bol. Mimeograf. Obs.
Tonantzintla Tacubaya); there are four codes - GG, IC, M and S - with the
authors as follows: GG = G. Gonzales and G. Gonzales, IC = B. Iriarte and E.
Chavira, M = L. Munch or L. Munch and W.W. Morgan (M3 only), and S = E.
Chavira. The individual codes refer to the following references:

LS
Luminous Stars (LS) number, from one of 6 possible papers where LS i
=Luminous Stars in the Northern Milky Way i, Hamburg-Bergedorf. Thus, if ls =
'1+59 38', the full correct name would be LS I +59 3. The references
corresponding to the 6 initial numerical (i) codes are as follows:

Spect_Type_Code
A crude spectral classification using the following codes:
Type Code Category
-----------------------------------------------------------

O, B, A, F of unknown luminosity class
O, B, A, F # of MK Class III, IV or V
CO, CB, CA, CF # of MK Class I or II
OF Of
WR, WC, WN, WP Wolf-Rayet
SB subluminous B
UG U Gem or Z Cam
Q old nova
RQ recurrent nova
X identified with an X-ray source
Z symbiotic
CQ super luminous nova-like variable
BQ, AQ, FQ shell component present in spectra
Y central star of a planetary nebulae
+ binary star
[] spectrum has shown forbidden emission lines
There are 1424 (26.7%) sources which have no spectral classification but are
presumed to be of early type. There are 732 stars with MK luminosity
classification, 420 binaries and 67 with forbidden lines in their spectra.
The '#', changed from '*' (asterisks) in the original file per HEASARC standard, denotes the availability of an MK luminosity classification from the Catalogue of Stellar Spectra classified in the Morgan-Keenan System (Jaschek, C., Conde, H. and de Sierra, A. 1964, University of La Plata Observatory, La Plata).
Vmag
The apparent visual magnitude in a band specified by the value of the
parameter vmag_flag.
Vmag_Flag
A flag regarding the visual magnitude value. If empty, the magnitude is
derived from photography (notice this is never stated explicitly in the paper
or the ADC/CDS documentation), if set to 'P' the magnitude is a photometric
magnitude in either the Johnson-Morgan V band, or (if available) for
Wolf-Rayet stars, the Smith-Weterlund v band, and if set to 'V', the
magnitude is variable.
Bmag
The apparent blue magnitude in a band specified by the value of the parameter
bmag_flag.
Bmag_Flag
A flag regarding the blue magnitude value. If empty, the magnitude is derived
from photography (notice this is never stated explicitly in the paper or the
ADC/CDS documentation), if set to 'P' the magnitude is a photometric
magnitude in either the Johnson-Morgan B band, or (if available) for
Wolf-Rayet stars, the Smith-Weterlund b band, and if set to 'V', the
magnitude is variable.
Class
Browse classification, derived from the spectral classification parameter
spect_type_code. Since this latter is a crude classification, the class
derived from it is equally crude.
